Insider Trading is a weekly report of stock transactions involving officers, directors and owners of 10 percent or more of a publicly held company.

Corporate insiders historically make more economically sound decisions in trading their own company's stock than do other investors. Insider trading activity also is often a bellwether of corporate health. Most insiders buy stock or exercise options to make a profit.

On the other hand, selling by insiders is not necessarily negative. Insiders may sell stock for tax reasons, estate planning or cash needs.

The following insider transactions involving companies with interests in Florida are the most recent reported to the Securities Exchange Commission and the New York and American stock exchanges.
